// Note: this .ctor should not contain any initialization logic.
}
public override void ViewDidLoad() {

DataTable table = GetValue(txtValue1.Text, txtValue2.Text);
foreach(DataRow row in table.Rows) {
lblValue1.Text = row[0].ToString();
lblValue2.Text = row[1].ToString();
}
}
partial void UIButton11_TouchUpInside(UIButton sender) {
DataTable table = GetValue(txtValue1.Text, txtValue2.Text);

alert.Show();
}
public DataTable GetValue(string v1, string v2) {
DataTable table = new DataTable();
table.Columns.Add("Value1", typeof(string));
table.Columns.Add("Value2", typeof(string));
table.Rows.Add(v1, v2);
return table;
}
public override void DidReceiveMemoryWarning() {
base.DidReceiveMemoryWarning();
// Release any cached data, images, etc that aren't in use.
